I had an issue with turning game mode on and after I was done and turned it off anything I played (movie or game) that has HDR would get crazy dimm. Had to reset the tv and it was fine... But when tried again with game mode same thing happened. So another factory reset. I haven't touched game mode since just to avoid having to reset. I've saved for so long to get an awesome flagship tv so I'm a little disappointed. Samsung please keep updating and fix these issues.
